[The Lost Slayer 01] • Buffy the Vampire Slayer - Buffy Season4 01

Buffy Summers' adjustment to life at U.S. Sunnydale has not gone smoothly. She feels awkward, insecure, and a bit jealous that Willow's all over the college life.

A unified troop of vampires has descended upon Sunnydale, operating with a cohesion unusual to most bloodsuckers.
